Dispersal patterns of Squamata in the Mediterranean: An evolutionary perspective

Abstract Mediterranean islands have a high diversity of squamates, although they are unevenly distributed. This variability in the composition of the reptile assemblages across islands may have been influenced by differences in the colonization abilities of these species. To evaluate the dispersal c...
